I have had the opportunity of examining an example of tlie 

 Aye-Aye, and find that the j)attern of the intestinal tract of that 

 animal resembles extremely closely the patterns exhibited by the 

 genus Lemitr, much more closely than the patterns of other 

 Lemurs. In this matter I completely confirm the conclusion of 

 Dr. Beddard fBeddard, 1908, Chiromys). A comparison of the 

 diagram of Chiromys (text-fig. 29) with that of a species of the 

 genus Lemur ^ (text-fig. 30) makes this i-esemblance plain. In

both the duodenal region is represented ' by two minor loops, 

 which in the Lemur were marked by a much greater calibre. 

 Meckel's tract was relatively rather short, and thrown into- 

 simple minor loops occupying the proximal portion of the 

 original pendant loop, but not reaching far beyond it. The 

 fore-gut enters at a right nngle to the cavity of the very 

 large caecum which is in wide continuity with that of the 

 dilated proximal portion of the hind-gut. In Leviur the

 i. hrunneus, the Black-headed Lemur, but the nomenclature of the Lemurs 

 requires revision.
